The jQuery strength.js plugin lets you measure the strength of password you typed in a text field,  and toggle the password field between plain text and password by click.

Installation:

# Yarn
$ yarn add jquery-strength

# NPM
$ npm install jquery-strength --save

How to use it:

1. The plugin requires fnando's password_strength library to validate the strength of your password:

<script src="/path/to/password_strength.js"></script>

2. Load the jQuery strength.js script after jQuery JavaScript library.

<script src="//code.jquery.com/jquery.min.js"></script>
<script src="jquery-strength.js"></script>

3. Call the function on the target password field and done.

<input type="password" class="password-input" name="password">
$(".password-input").strength();

4. By default, the plugin will automatically generate a checkbox to toggle the visible of your password text. You can customize the visible toggle in the JavaScript like so:

<input type="password" class="password-input" name="password">
$(".password-input").strength({
  templates: {
    toggle:
      '<span class="input-group-addon"><input type="checkbox" class="{toggleClass}" title="Show/Hide Password" /></span>'
  },
});
